How to Calculate Resistance of an Incandescent Lamp Filament
What information is given about an incandescent lamp filament in the data?
The data provides the voltage and current values for the incandescent lamp filament, which are 12 volts and 2 amps respectively.
What is the specific question related to the data?
What is the resistance of the filament of this lamp in working condition?
Answer:
The resistance is 6 ohms
Explanation:
Given: Voltage (V) = 12V Current (I) = 2A Using Ohm's law formula: Resistance (R) = V / I Resistance (R) = 12V / 2A Resistance (R) = 6 ohms
Calculating the resistance of an incandescent lamp filament is crucial in understanding its electrical properties. In this scenario, the voltage and current values provided allow us to apply Ohm's law to determine the resistance.
Ohm's law states that the resistance (R) of a component is equal to the voltage (V) across it divided by the current (I) passing through it. In this case, the voltage is 12V and the current is 2A, which gives us a resistance of 6 ohms.
By knowing the resistance of the filament, we can better understand how the lamp operates and how it interacts with the electrical circuit. This knowledge can be valuable for troubleshooting and maintenance purposes.
Understanding the basic principles of electricity, such as Ohm's law, empowers individuals to work with electrical systems safely and effectively. It also opens up opportunities for further exploration and learning in the field of electrical engineering.
